Abstract

A connecting structure of a box-type combination column and a concrete beam comprises a box-type combination column and a concrete beam, wherein the box-type combination column is provided with a rectangular steel pipe column. The connecting structure is characterized in that reinforcing plates are fixed on two of opposite surfaces of the rectangular steel pipe column at the node combination part of the box-type combination column and the concrete beam; the reinforcing plates and the side surfaces of the rectangular steel pipe column fixed with the reinforcing plates are provided with holes having the same quantity with longitudinal reinforcing bars of the reinforced concrete beam; the longitudinal reinforcing bars of the reinforced concrete beam pass through the holes; sleeves having the same quantity with the longitudinal reinforcing bars of the reinforced concrete beam are fixed on the other two opposite surfaces and connected with the surfaces; and the longitudinal reinforcing bars of the reinforced concrete beam penetrate into the sleeves. The connecting structure of the box-type combination column and the concrete beam has simple and flexible construction and can prevent the bumping of the reinforcing bars.

Description

The joint construction of box coupled column and concrete beam

[technical field]

The utility model includes the ordinary construction of the building of metal support member, refers to the joint construction of a kind of box coupled column and concrete beam especially.

[background technology]

The box coupled column is big owing to its cross section moments of inertia, performance steel bending resistance bearing capacity that can be best; Also can produce additional hoop effect to concrete, improve concrete cross section limit pressure-bearing effect, be the rod structure commonly used of present highrise building, the way of prior art is to give first boring on the post steel plate when being connected of the main up and down muscle of Vierendeel girder and post, and on-the-spot horizontal bar is penetrated in the hole.This method shortcoming is: 1, bore position is difficult to adapt with on-the-spot reinforcement location, gives reinforcing bar binding the difficulty greatly of bringing in place.2, on-the-spot bar diameter and radical have Iso moving, and the hole can not change, the The field inconvenience.3, two mutually orthogonal directions of post side all have beam, and in the time of all will wearing muscle, they all are in same absolute altitude, wear muscle by the hole and just make reinforcing bar " fighting " mutually, and this is its shortcoming.

[summary of the invention]

At the shortcoming of prior art, the purpose of this utility model is to provide a kind of structure construction simple, flexible, can not produce the box coupled column of mutual " fighting " phenomenon of reinforcing bar and the joint construction of concrete beam.

The technical scheme that its technical problem that solves the utility model adopts is: include box coupled column and reinforced concrete beam, the rectangle steel tubing string is arranged in the box coupled column, it is characterized in that: in the node junction of box coupled column and reinforced concrete beam, the rectangle steel tubing string wherein be fixed with stiffening plate on two opposites, described stiffening plate and fixing with it rectangle steel tubing string side have the hole that equates with reinforced concrete beam longitudinal reinforcement quantity, and described reinforced concrete beam longitudinal reinforcement passes these holes; Be fixed with the equal sleeve of reinforced concrete beam longitudinal reinforcement number that is connected with this face on other two opposites of described wherein two opposites, described reinforced concrete beam longitudinal reinforcement penetrates in these sleeves.

Described fixing can be that welding is fixing.Can adopt to be threaded between described reinforced concrete beam longitudinal reinforcement and sleeve to penetrate, the reinforced concrete beam longitudinal reinforcement is tightened in the sleeve with screw thread, and sleeve is welded in rectangle steel tubing string side.

Generally can select the long limit perforate of rectangular steel pipe column section, and the minor face welded sleeve of rectangular steel pipe column section.

The rectangle steel tubing string can be provided with the stringer plate in the position corresponding to the reinforced concrete beam longitudinal reinforcement in rectangle steel tubing string inboard at reinforced concrete beam longitudinal reinforcement and its weld, prevents that rectangular steel pipe post jamb part is subjected to curved unstability.

Can also add vertical internal-rib on inboard this limit of rectangle steel tubing string.Generally speaking when the rectangle steel tubing string length of side big (

The time, the ho-web calculates high; The tw-web is thick; Fy-steel yield strength.) time, add vertical inner rib plate on inboard this limit of rectangle steel tubing string.

The beneficial effects of the utility model are: structure construction is simple, flexible, can not produce reinforcing bar " fighting " phenomenon mutually.

[specific embodiment]

Referring to accompanying drawing, the utility model includes box coupled column and reinforced concrete beam, the rectangle steel tubing string is arranged in the box coupled column, it is characterized in that: in the node junction of box coupled column and reinforced concrete beam, rectangle steel tubing string 1 wherein be fixed with stiffening plate 2 on two opposites, described stiffening plate 2 and fixing with it rectangle steel tubing string 1 side have the hole 3 that equates with reinforced concrete beam longitudinal reinforcement 4 quantity, and described reinforced concrete beam longitudinal reinforcement 4 passes these holes 3; Be fixed with the equal sleeve 7 of reinforced concrete beam longitudinal reinforcement 6 numbers that is connected with this face on other two opposites of described wherein two opposites, described reinforced concrete beam longitudinal reinforcement 6 penetrates in these sleeves 7.

In embodiment of the present utility model, described fixedly is that welding is fixing.Described reinforced concrete beam longitudinal reinforcement 6 adopts with sleeve 7 and is threaded, and reinforced concrete beam longitudinal reinforcement 6 usefulness screw threads are tightened in the sleeve 7, and sleeve 7 is welded in rectangle steel tubing string 1 side.

In embodiment of the present utility model, rectangle steel tubing string 1 is at reinforced concrete beam longitudinal reinforcement and its weld, and the position in rectangle steel tubing string inboard corresponding to the reinforced concrete beam longitudinal reinforcement is provided with stringer plate 5.
